I am trying to make changes to our navigation bar. I first open in Contribute my homepage and then I go to edit the page in Dreamweaver. I make changes to the navigation bar but then when I go back to Contribute and preview or publish it removes my changes and goes back to the old navigation bar. Please help! My programming friend said it might be a permission problem because someone else did the original structure and build for the website, but this is for a company that he only does contracted work for so I am not sure this is the case. See code below:
